title: [Value of a velocimetric study of the uterine arteries in retroplacental hematoma. 3 case reports].
abstract: Retroplacental hematoma is a sudden event with a poor prognosis, the latter being aggravated by the very frequent lack of predictive clinical, laboratory or echographic signs. Does studying the velocity of blood flow in uterine arteries have a predictive value in this disease? The equipment used was a continuous Döppler with spectral analysis and probe of 4 MHz, without echographic identification. Each examination systematically included the study of the 2 uterine arteries and the umbilical flow. The technique for recording flow in the uterine arteries is described. A report is given of three cases of retroplacental haematoma. An increase in the resistance index in one of the uterine arteries was found in the three cases (twice on the right, and once on the left), with a protodiastolic notch on the curve, whereas the umbilical index itself was normal and there were no other sign that indicated the placental event. The Döppler is already known to be of value in numerous indications in obstetrics: it should be possible to extend these indications even further, particularly if this preliminary study is confirmed on a broader scale.
